uClinux question

Hello, 

 

i just started to work with uClinux on an altera eval board. 

 

I have a question regarding uClinux. 

 

Does uClinux when running on a nios system have it's own compiler built-in? 

 

Particularly what compiler do application on uclinux use? 

 

I,m a just a beginner and would like to learn this.

uClinux running on board doesn't have GCC included in. Applications must be cross-compiled on a host Linux machine using Nios II binary tools (same used to compile kernel).  

 

These are the precompiled tools.

So, your application can be added to your system in two ways: 

 

* Adding application during kernel compilation. 

 

* Adding the compiled application to your uClinux file-sytem through a storage device (USB pendrive, SD card) or a Network filesystem.

I suppose it is somehow possible to ccross-compile the gcc compiler to have it run on the NIOS itself, such as there is a Debian Linux distribution that runs on ARM and can d/l additional packets in source code and compile and install them.  

 

But I don't think anybody would bother to do that for a deeply embedded arch like NIOS, as it does not make much sense.

For embedded systems, to have their own self-compiler means the War of Independence for PC Imperial.:D But to get the true independence, we must obtain a Thoroughbred gcc. This means to rebuild the 'nios2gcc' on Nios system....:p
